Firmware updates for blockchain-connected IoT devices demand secure, tamper-proof delivery. This mechanism uses blockchain to log update hashes, ensuring authenticity via consensus. Devices verify updates through threshold signatures from authorized publishers before installation. Lightweight cryptographic primitives suit resource-constrained devices, while multi-party computation (MPC) distributes key management. Rollback protections prevent downgrade attacks, maintaining device security across update cycles in distributed IoT networks.
